Examples

Example #1 Object oriented style

<?php
$maxdb 
= new maxdb("localhost""MONA""RED""DEMODB");

/* check connection */
if (maxdb_connect_errno()) {
   
printf("Connect failed: %s\n"maxdb_connect_error());
   exit();
}

$query "SELECT name, cno from hotel.customer ORDER BY cno";

if (
$result $maxdb->query($query)) {

   
/* Get field information for all columns */
   
while ($finfo $result->fetch_field()) {

       
/* get fieldpointer offset */
       
$currentfield $result->current_field;

       
printf("Column    %d:\n"$currentfield);
       
printf("Name:     %s\n"$finfo->name);
       
printf("Table:    %s\n"$finfo->table);
       
printf("max. Len: %d\n"$finfo->max_length);
       
printf("Flags:    %d\n"$finfo->flags);
       
printf("Type:     %d\n\n"$finfo->type);
   }
   
$result->close();
}

/* close connection */
$maxdb->close();
?>

Example #2 Procedural style

<?php
$link 
maxdb_connect("localhost""MONA""RED""DEMODB");

/* check connection */
if (maxdb_connect_errno()) {
   
printf("Connect failed: %s\n"maxdb_connect_error());
   exit();
}

$query "SELECT name, cno from hotel.customer ORDER BY cno";

if (
$result maxdb_query($link$query)) {

   
/* Get field information for all fields */
   
while ($finfo maxdb_fetch_field($result)) {

       
/* get fieldpointer offset */
       
$currentfield maxdb_field_tell($result);

       
printf("Column    %d:\n"$currentfield);
       
printf("Name:     %s\n"$finfo->name);
       
printf("Table:    %s\n"$finfo->table);
       
printf("max. Len: %d\n"$finfo->max_length);
       
printf("Flags:    %d\n"$finfo->flags);
       
printf("Type:     %d\n\n"$finfo->type);
   }
   
maxdb_free_result($result);
}

/* close connection */
maxdb_close($link);
?>

The above example will output something similar to:

 Column 1: Name:  NAME Table: max. Len: 10 Flags: -1 Type:  2 Column 2: Name:  CNO Table: max. Len: 4 Flags: -1 Type:  0
